Answer:
Rotations of tire to travel 500 feet: 95.54
Step-by-step explanation:
Circumference = 20 x 3.14 = 62.8 in
500 feet = 500 x 12 inches = 6,000 in
Rotations = 6000 / 62.8 = 95.54 rotations of tire
Answer:
C. 20(1/2)
Step-by-step explanation:
Let's find the value of the expression before looking for the nearest estimate
(19 4/5) (4/6) = 19 *(4/5)(4/6)
(19 4/5) (4/6) = 19(16/30)
(19 4/5) (4/6) = 19(8/15)
(19 4/5) (4/6) = (19*8)/15
(19 4/5) (4/6) = 152/15
(19 4/5) (4/6) = 10(2/15)
A. 16(1/3) =5.33
B. 19(2/3) = 12.667
C. 20(1/2) = 10
D. 20(1)= 20
The nearest to the expression is C. 20(1/2)
Answer:
k=9
Step-by-step explanation:
First find r=22/20=1.1
The sum of the first k terms formula is a1•(1-r^k)/(1-r)
a1=20 and the sum is 271.59
Now plug in these values in the formula and find k.
271.59=20(1-1.1^k)/(1-1.1)
When you simplify this equation, you will get k=ln(2.358)/ln(1.1)
k=9
Your answer is 50
Six was multiplied by 10 so you do the same to 5 which 5 times 10 is 50
